Scientists outline nerve ache or neuropathy as any situation through which a person has sustained injury to their nerves.
This text appears to be like on the essential sorts of drugs for neuropathy, discussing which have probably the most optimistic results. It additionally considers what the science has to say about nonpharmacological therapies for this situation.
Anticonvulsants are first-line drugs that assist handle the signs of seizure problems, akin to epilepsy.
As a 2022 assessment explains, these medicine can work in numerous methods. One essential mechanism of motion entails the ion channels, that are cell parts that regulate cell operate by letting mineral ions out and in.
A 2017 paper means that some anticonvulsants are among the many only drugs for neuropathic ache. These first-line neuropathy drugs act on particular ion channels that visitors calcium ions. They embrace gabapentin (Neurontin) and pregabalin (Lyrica).
Though they’re typically efficient, these drugs could cause hostile results.
A 2019 assessment lists the next attainable unwanted side effects of each gabapentin and pregabalin:
Gabapentin also can result in blurred imaginative and prescient, whereas pregabalin could cause weight achieve.
An individual ought to seek the advice of a physician in the event that they discover these signs after taking anticonvulsants.
Scientists additionally contemplate some antidepressants to be a first-line remedy for neuropathic ache. The simplest antidepressants for neuropathic ache are tricyclic antidepressants (TCAs) and serotonin–noradrenaline reuptake inhibitors (SNRIs).
Nonetheless, these drugs also can produce unwanted side effects.
Amitriptyline is a TCA that may assist individuals handle nerve ache. Nonetheless, it could actually result in a number of negative effects, together with:
In uncommon circumstances, some individuals might have severe unwanted side effects after taking amitriptyline. These might embrace:
Duloxetine and venlafaxine
Examples of SNRIs embrace duloxetine (Cymbalta) and venlafaxine (Effexor). A 2018 research demonstrated that duloxetine was more practical than venlafaxine in lowering the signs of chemotherapy-induced peripheral neuropathy.
Nonetheless, these medicine may end up in unwanted side effects.
Duloxetine could cause:
- dry mouth
- difficulties with:
The attainable unwanted side effects of venlafaxine embrace:
Folks ought to converse with a physician if they’re experiencing unwanted side effects which are affecting their high quality of life.
Consultants contemplate sure opioids to be a second-line remedy choice. A 2022 assessment notes that opioids act on calcium and potassium ion channels to provide pain-reducing results.
Tramadol (Ultram) and tapentadol (Nucynta) are opioids that may assist with neuropathic ache. Nonetheless, there may be proof that each drugs could cause unwanted side effects, a few of that are severe. These embrace:
Docs are much less eager to prescribe stronger opioids for neuropathic ache. Stronger opioids for neuropathy embrace morphine and oxycodone, which trigger related unwanted side effects as these above.

The choices embrace lidocaine — a sort of native anesthesia — and capsaicin patches.
Lidocaine causes ache aid by performing on sodium ion channels. Nonetheless, lidocaine patches could cause a rash, erythema, and itching.
Analysis has additionally proven that capsaicin, which happens naturally in chili peppers, acts on each calcium and sodium ion channels. As with lidocaine, capsaicin patches can result in erythema and itching. In uncommon circumstances, they could additionally trigger ache and hypertension.
Find out about the most effective capsaicin lotions.
In some circumstances of neuropathic ache, docs might advocate that a person take a number of drugs without delay. Nonetheless, the proof for the effectiveness of mixed remedy stays inconclusive.
A 2017 research means that sure drug mixtures may be helpful. As an illustration, taking an anticonvulsant, akin to gabapentin or pregabalin, alongside a TCA antidepressant may very well be more practical than taking both sort of drug alone.
Combining totally different medicine typically supplies improved ache aid and tolerability.
Nonetheless, ample proof has not but emerged to verify that mixture remedy is more practical than monotherapies.
Regardless of medical advances, pharmacological therapies for neuropathic ache might solely be efficient in lower than 50% of circumstances. Due to this fact, many individuals search different sources of remedy for this situation.
There’s restricted proof that nonpharmaceuticals are useful on this regard.
Nonetheless, a current remedy overview means that spinal twine stimulation (SCS) remedy may relieve nerve ache in circumstances the place pharmaceutical therapies have confirmed ineffective. SCS remedy entails stimulating an individual’s spinal twine with electrical impulses. Docs obtain this by inserting small electrodes into the backbone, utilizing both surgical procedure or an epidural needle.
Docs might prescribe numerous medical therapies for nerve ache, together with antidepressants, anticonvulsants, opioids, and topical drugs.
In some circumstances, they could advocate a number of therapies without delay. Nonetheless, the present analysis has not decided whether or not it’s more practical than a single remedy.
